By 'match' I guess you mean blink on the beginning-< when an end > is
inserted. This is because I removed <> and () from the emacs syntax
table for .ly files.  The built-in parenthesis-matching function relies 
on the syntax table to determine what is a paren. 

However in lily, to make indentation and fontifying work properly with
accents or dynamic markings in chords (e.g. < f \> a c-> > ), we need a
regexp to denote a member of a parenthesis-pair. Emacs syntax tables
will only accept single characters (or double characters, in the case of
comments).  A similar problem occurs with () meaning either Scheme or a
phrasing-slur, depending on context, and the emacs syntax table
doesn't understand context. 

I suppose a solution might be to write a lily-specific paren-blinking
function. 

(meanwhile this patch will take care of [ ] ...)
